在测定铁岭挽马血液生化指标和生产性能的基础上,分析了它们之间的复相关,利用通径分析原理找出了直接影响速力的主要血液生化指标为α—球蛋白、LDH_4、肌酐、无机磷、Ca~(++)、血糖、Na~+、LDH_5。对其进行了逐步回归分析,经显著性检验,通径系数达到极显著者,建立了最优回归方程,此方程中血液生化指标与速力的复相关系数 (R=0.9120)很大,误差项(d_(ye)=1—∑d)很小,说明上述主要血液生化指标的性状选种,具有一定的应用价值。
Based on the determination of blood biochemical indexes and production performance of Tieling wang, the complex correlation between them was analyzed. The main blood biochemical indexes that directly influenced the tachycardia were identified as α-globulin, LDH 4, creatinine, Inorganic phosphorus, Ca ~ (++), blood glucose, Na ~ +, LDH_5. A stepwise regression analysis was carried out. Significant tests showed that the path coefficient reached a very significant level, and the optimal regression equation was established. The complex correlation coefficient (R = 0.9120) between the blood biochemical indices and the rapid force was large. The error term (d_ (ye) = 1-Σd) is small, indicating that the above blood biochemical indicators of the characteristics of selection, has a certain application value.
